A new report finds that the United States could more efficiently produce food if half the country's protein supply came from plant-based or alternative proteins rather than meat or dairy. The analysis demonstrates how a shift toward a plant-based diet provides ample benefits for the environment and the climate.
In its latest report, the Good Food Institute, or GFI — a nonprofit think tank that supports the growth of alternative proteins — calculates that if Americans replaced 50 percent of their animal protein consumption with plant-based options, then 47.3 million fewer acres of cropland would be needed to grow the same amount of protein. That land, which altogether makes up an area roughly the size of South Dakota, represents tremendous opportunities for carbon sequestration and biodiversity, according to GFI.
The organization argues that if those acres weren't used to grow crops, they could instead be transformed into carbon sinks or used to restore threatened ecosystems. That would deliver climate benefits on top of the reduction of animal agriculture's more direct emissions sources: manure and cow burps. The U.
S. currently devotes a tremendous amount of land to agriculture: Over 60 percent of land in the contiguous U.S.
is used for agriculture, and 21 percent of that is cropland. A majority of the nation's cropland — 78 percent — is used to raise crops that are pri.
